This squeaky clean space on the 6th floor has everything but the computers. Note the absence of raised floors. In this facility, servers will be placed on concrete slabs. Air supply travels through the walls from the computer room air handler units that can be adjusted as necessary.
The 5th floor houses the data center's uninterruptable power supply systems and backup batteries. The UPS room itself is redundant, too. There are four of these UPS rooms.
The chiller plant on the 4th floor of the data center is comprised of condenser water pumps and risers that are responsible for maintaining the appropriate temperature in the data center. The ceilings in this area are 23 feet high. As the temperature cools down outside the building, the chillers can be dialed back.
